IZI

' 5 the lever 30 for closin t 30 time is very slight,

In operation of vthe dropped into the coin tube 25 and falls downward until arrested by the pin 32. In this position of theecoin it presses against an electric, circuit thru the lamp 64 and t ru the electric motor 40. The lamps light for providing illumination and the electric motor 40 operates for turning the shaft 81 nearly thru a com lete revolution.

During turning of the shaft 81 thru the said portion of a revolution the rod 52 is Ioperated for dispensing a cup. The make and break 43 is also turned thru slightly this make and break which breaks the circoin which next drops'down along the coin tube 25. 2B As the coin passes the delay lever 66 and the switch lever 67 it momentarily c loses a circuit thru the lamps 64 for again lighting the lamps, and thru the electrlc motor 40. The motion of the electric motor this just suiiicient lto notate the make and break 43 slightly so as to complete one revolution when taken together with itsl incompleted revolution. uring the slight second action of the motor a 35 cam 104 acts against the pin 107 for momentarily opening the valves 120 and 121 so that the Water and fruit juice drawn rointhe containers 126 and 127 may discharge into the large bowl 130.

Attention is called that the cain 104 is so the valves 120 and 121 reconstructed that short period of4 time,

main open for a very but this is suliicient to discharge thedesired quantity of liquid. Then the liquid contained in the bowl 130 may flow thru the passages connected with the bowl -so as to discharge from the spout 60 and fill the cup 59. The spring 72 may be ad]ustably tensioned so as to change the delay of the coin passing thru the coin tube 25 and acting against the lever 71, so as to vice for obtaining a full cup of the drink dispensed.

While we have shown'and described a preferred embodiment of our invention, it is to be understood that we do not limit ourselves to the preciseconstruction herein disclosed and the ri ht is reserved to all changes and modi cations coming within the scope of the invention as defined in the appended claims, and tothe rights of using a plurality of pa er cup devices' also to a plurality of lqui vending units.
